Greeting from Leadsoc Technologies _ Bangalore.

Position: BLE Controller Software and Firmware Engineer Skills :

Design and develop BLE Link Layer and MAC controller software.

Implement advertising, scanning, initiating, connection establishment and connection-event processing.

Develop packet scheduling, channel selection, frequency hopping, acknowledgements, retransmission and timing-control functions.

Interface BLE Link Layer software with radio PHY, hardware registers, timers, DMA and interrupts.

Develop controller firmware, startup software, hardware-abstraction layers and peripheral drivers.

Implement low-power states, sleep/wake-up handling, clock management and power optimization.

Develop and integrate HCI transport over UART, SPI, USB or shared memory, as applicable.

Support Direct Test Mode, manufacturing test modes, diagnostics and RF validation.

Debug protocol timing, interoperability, throughput, latency, buffer-management and power-consumption issues.

Develop unit tests and participate in integration, conformance and interoperability testing.

Work closely with RF, ASIC, FPGA, validation, application and upper-stack teams.

Support design reviews, code reviews, defect resolution and technical documentation.

Required Skills

3-5 years of experience in embedded firmware, wireless protocol software or BLE controller development.





Solid programming skills in Embedded C; working knowledge of C++ is desirable.

Hands-on experience in BLE Link Layer, MAC, controller firmware or closely related protocol-stack development.

Understanding of BLE advertising, scanning, initiating, connections, connection parameters, data channels and control procedures.

Knowledge of BLE packet formats, access addresses, CRC, whitening, channel mapping and adaptive frequency hopping.

Understanding of BLE PHY interaction and time-critical radio-event scheduling.

Experience with RTOS or bare-metal embedded software development.

Familiarity with ARM, RISC-V, DSP or similar embedded processor platforms.

Experience with JTAG debuggers, protocol analyzers, logic analyzers and oscilloscopes.

Working knowledge of the Bluetooth Core Specification 5.x or later.

Preferred Skills

Knowledge of HCI, L2CAP, SMP, ATT, GATT, DTM and controller-host architectures.

Experience in pre-silicon FPGA/emulation or post-silicon validation environments.

Exposure to BLE qualification, RF conformance, interoperability testing and test automation.

Knowledge of AES-CCM, pairing, bonding, key handling, OTA updates and secure bootloaders.

Experience : 3- 5 yrs
